A report Thursday on Cape Wind and energy prices misconstrued the price of offshore and onshore wind energy. Nationally, the Department of Energy estimates that in 2012 the total cost to construct an onshore wind-powered electric generating system will be $2,090 per kilowatt of system capacity, as compared to an offshore wind facility, which is projected to cost $5,440 per kilowatt of capacity. ISO-New England also sells power, or megawatt hours, not energy.

Additionally, the report incorrectly attributed a quotation: Mark Rogers, spokesman for Cape Wind, said the prices of renewable energy are generally more expensive because of construction costs and that more research and development will bring the prices of offshore energy down.
